2. Check the fuel level.
Your engine is designed to use any gasoline that has a
pump octane number ( 9 ) of 86 or higher, or that
has a research octane number of 91 or higher. Gasoline
pumps at service station normally display the pump
octane number.
We recommend that you use unleaded fuel because it
produces fewer engine and spark plug edposits and
extends the life of exhaust system components.
Never use stale or contaminated gasoline or an oil/
gasoline mixture. Avoid getting dirt, dust or water in
the fuel tank. Use of a lower octane gasoline can cause
persistent "pinging" or heavy "spark knock" (a metal-
lic rapping noise) which, if severe, can lead to engine
damage.
)cALITIoN]
If 'Spark knock" or 'pinging" occurs at a steady
engine speed under normal load, change brands of
gasoline. If spark knock or pinging persists, consult
your authorized Honda dealer. Failure to do so is
considered misuse, and damage caused by misuse is
not covered by Honda's Limited Warranty.
Occasionally you may experience light spark knock
while operating under heavy loads. This is no cause
for concern, it simply means your engine.is operating
efficiently.
* Gasoline is extremely flammable and is explosive
under certain conditions.
l
Refuel in a well-ventilated area with the engine
stopped. Do not smoke or allow flames or sparks in
the area where the engine is refueled or where
gasoline is stored.
* Do not everfilr the tank (there should be no fuel in
the filler neck). After refueling, make sure the tank
cap is closed properly and securely.
* Be careful not to spill fuel when refueling. Spilled
fuel or fuel vapor may ignite.
If
any fuel ti spilled,
make sure the area is dry before starting the
engine.
l
Avoid repeated or prolonged contact with skin or
breathing of vapor. KEEP OUT OF REACH OF
CHILDREN.
